Nurses' Interpretation of Force Fluids
… of a minimum and maximum amount of fluid in the order "Force fluids", and (2) determine criteria most used by these nurses to identify the fluid quantities.</p> <p>The descriptive survey was the method of study. A questionnaire, which centered around recorded chart information for …

Portable magnetic resonance sensors and methods for noninvasive disease diagnostics
Many diseases manifest as a shift in fluids between distinct tissue fluid compartments. For example, fluid depletion and fluid overload lead to a deficit or accumulation of fluids within the intramuscular interstitial space. A direct measurement of these fluid shifts could serve as a highly …

Capillary pressure curve and liquid permeability estimation in tight oil reservoirs using pressure decline versus time data
… during the experiment could be used to estimate fluid saturations as a function of time which can be very useful in determining relative permeability curves in the shale. This new procedure is easy, fast and can be reversed to estimate imbibition curves as well. It can be applied to both …

The influence of micro-porosity on drainage relative permeability using digital core analysis
… resolution. The importance of micro-pores in fluid flow and solute transport has often been ignored. In this study, we quantify and couple the effect of sub-resolution pores into larger pores for different porous media with varying amount of micro- to macro-porosity. Both single phase and …

Hydraulic flow zone unit characterisation and mapping for Australian geological depositional environments
… of giving improved estimates of reservoir fluid distributions, has been proposed. The new methodology is particularly well suited for interpolating among different lithologies and diverse rock types as evident from comparison with other methods reported in the literature. In conclusion, …

Impedance Sensors for Fast Multiphase Flow Measurement and Imaging
… sensor. The sensor is able to discriminate fluids with different relative permittivity (dielectric constant) values in a multiphase flow and achieves frame frequencies of up to 10 000 frames per second. The third sensor introduced in this thesis is a planar array sensor which can be employed …

Formulation and Implementation of a Constitutive Model for Soft Rock
… failure mechanisms; rate-dependence; and pore fluid dependence. The research described in this dissertation was performed with the objectives to formulate a constitutive model which describes all aspects of chalk and soft rock mechanical behavior, develop and/or implement methods to integrate …

Quantitative monitoring of gas injection, exsolution and dissolution using 4D seismic
… a qualitative estimate of the moved subsurface fluids; exact quantitative evaluation of fluid distributions and associated saturations remains a challenge still to be solved. It is widely believed that a few percent of gas makes the pore fluid mixture very compressible, so that it cannot be …
